14 - FUEL SYSTEM/FUEL DELIVERY - STAN-
DARD PROCEDURE).
2. Disconnect the negative battery cable.
3. Remove timing belt (Refer to 9 - ENGINE/VALVE
TIMING/TIMING BELT/CHAIN AND SPROCKETS -

BELT-TIMING AND SPROCKETS
REMOVAL
TIMING BELT
CAUTION: The 3.5L is NOT a freewheeling engine. Therefore, loosen the valve train rocker assemblies
before servicing the timing drive.
1. Perform fuel pressure release procedure. (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY - STANDARD PRO-
CEDURE).
2. Disconnect negative battery cable.
3. Remove both cylinder head covers and loosen the rocker arm assemblies (Refer to 9 - ENGINE/CYLINDER
HEAD/ROCKER ARM / ADJUSTER ASSY - REMOVAL).
4. Remove the front timing belt cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) -
REMOVAL).
5. Mark belt running direction, if timing belt is to be reused.
CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will
result in valve and/or piston damage.
6. Rotate engine clockwise until crankshaft (10) mark aligns with the TDC mark on oil pump housing (9) and the
camshaft sprocket (2, 7) timing marks (1, 8) are aligned with the marks on the rear cover.
7. Remove the timing belt tensioner (12) and remove timing belt.

8. Inspect the tensioner for fluid leakage.
9. Inspect the pivot and bolt for free movement, bearing grease leakage, and smooth rotation. If not rotating freely,
replace the arm and pulley assembly.
10. When tensioner is removed from the engine it is
necessary to compress the plunger into the ten-
sioner body.
CAUTION: Index the tensioner in the vise the same
way it is installed on the engine. This ensures
proper pin orientation when tensioner is installed
on the engine.
a. Place
the
tensioner into
a
vise (1) and
SLOWLY compress the plunger. Total bleed
down of tensioner should take about 5 min-
utes.
b. When plunger is compressed into the tensioner
body install a pin (2) through the body and
plunger to retain plunger in place until ten-
sioner is installed.
CAMSHAFT SPROCKETS
CAUTION: The 3.5L engine is NOT a free-wheeling
design. Therefore, care should be taken not to
rotate the camshafts or crankshaft with the timing
belt removed.
NOTE: The camshaft timing gears are keyed to the
camshaft.
1. Perform fuel pressure release procedure. (Refer to
14 - FUEL SYSTEM/FUEL DELIVERY - STAN-
DARD PROCEDURE).
2. Remove front timing belt cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
3. Position crankshaft sprocket to the TDC mark on
the oil pump housing by turning crankshaft in the
clockwise direction.
4. Install a dial indicator in number 1 cylinder to check TDC of the piston. Rotate the crankshaft until the piston is
at exactly TDC.
5. Remove camshaft retainer/thrust plate (1) from rear of right cylinder head.
6. Remove the right cylinder head cover.
7. Remove the right rocker arm assembly.
8. Remove the timing belt tensioner and timing belt.
